Contact Factory for availability. 2This board can be used as a standalone evaluation board or in conjunction with the EVAL-CONTROL BRD2 for evaluation/demonstration purposes. 3This board allows a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designator. CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although WARNING! the AD7650 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are ESD SENSITIVE DEVICE recommended to avoid performance degradation or loss of functionality. REV. 0 –5–
